Summary:
Mapleton, Minnesota has just one elementary school in this data set — Maple River Elementary, which serves grades PK–5 with 424 students and belongs to the Maple River School District; because it is the only elementary school in the city, it carries Mapleton's entire elementary profile, and the most useful comparisons are against its district, the state, and its own past results.
Academically, math is this school's clearest strength. In 2025-2026, all-grades math proficiency was 55.5%, compared with 44.9% statewide and 53.3% in the district, and 3rd-grade math reached 67.6% versus 57.9% statewide. Science was also above the state at 28.8% (state: 25.5%), though below the district's 35.6%. Reading was the softer spot: all-grades reading was 47.6%, about 1 point under the state and 2.7 points under the district, with 3rd-grade reading at 37.8%, which was 9 points below the state. Reading results were not uniform, however — 5th-grade reading was 60.6%, 6.1 points above the state, and 5th-grade math at 40.9% was roughly in line with the state's 41.9%.
The trend lines are worth watching. The school declined year over year in all three subjects — math from 60.1% to 55.5%, reading from 50.96% to 47.6%, and science from 39.71% to 28.8% — with science showing the largest single-year drop at nearly 11 percentage points. Its state rank slipped from the 74th percentile and 4 stars in 2023-2024 to the 57th percentile and 3 stars in 2025-2026. That contrasts with the Maple River School District, ranked 62nd of 458 districts (86th percentile, 4 stars), suggesting district strength may come from other schools or grade levels. For parents, the takeaway is a school that remains above the state in math and science, with notable bright spots in 3rd-grade math and 5th-grade reading, but where reading and recent science momentum are the areas to watch.
